01' CHEMNITZ, GERMANY DEVICE FOR THE WET TREATMENTS OI BANKS AND THE LIKE Application filed January 18, 1929, Serial No. 383,005, and in Germany August 14, 1928.

' In the wet treatments of hanks, for example in the dying of hanks of yarn or other textile material, it is usual to place the said hanks over shafts which are rotated by pairs 5 of rollers at their ends, and to transfer the same periodically from one pair of such rollers to the next. Owing to the fact that the said rollers rotate all at the same speed, the shafts are also rotated all at the same speed and consequently the hanks of yarn suspended therefrom are all moved backward and forward bythe same amount. This results in that each hank ,of yarn always turns at exactly the same place upon each of the successive shafts.

It is the main object of this invention to avoid this drawback and to enable the turning of the hanks at different places of their lengths upon each of the rotating shafts and 2 the invention, therefor, consists of simple and eflicient means for imparting different speeds to the various driving rollers, or groups or pairs of driving rollers, and their reversing places are distributed over considerably greater portions of the hanks as has been the case heretofore. Thus the hanks will no longer be strained always at the same place as in the known arrangements, but always at new places, so that the finished hank will have an even appearance over its entire length.

Other objects and improvements of the invention will be apparent from the following description of the example shown in the accompanying drawings, in which Fig. 1 is a diagrammatic view of a train of rollers and shafts in side elevation, and

Fig. 2 a broken-oil end view of Fig. 1, likewise diagrammatic; the rollers in both views being shown in communication with their drivin means.

In t ese drawings 1 is used to 'denote the rotating shafts'from which the hanks'of yarn .or the like are suspended, and which are provided at their ends with discs 2 adapted to rest loosely upon the groups of rollers 3, 3;

4,4 5, 5 and 6, 6', which are rotated in unison from a longitudinal shaft 7 and an intermediate gear such as will be described hereafter.

According to the invention the co operating groups of rollers are driven at different speeds and it is evident, that various means to achieve this purpose may be employed. One way, for example, consists in making the said rollers of different diameter as illustrated bythe pairs of rollers marked 3, 3 and 4, 4 respectively, of which the former are smaller than the latter. Another way is p to change the ratio in the driving means for the various pairs of rollers, for example, by making the gear wheel 26 of different 'diameters as is indicated in the case of the rollers 4, 4' and 5, 5'.

It is further possible to achieve the desired result by maintaining the ratio of the various gear wheels and using different kinds of gear, as for example worms and worm wheels having threads of varied pitch, such as indicated by the driving gears of the rollers 6, 6.

It is to be understood, that the invention is not intended to be limited to the examples shown and described, but that the same may be altered or modified to suit various purposes or requirements without departing from the spirit of the invention as pointed out in the following claims. 1

What I claim is 1. A device for the wet treatment of hanks and the like, comprising rotary shafts to movably suspend the hanks to be treated, and means torotate the said shafts and the hanks suspended therefrom at mutually different 5 eeds.

2. In a device for the wet treatment of banks and the like, a number of rotary shafts to movably suspend the hanks to be treated, rollers arranged in groups to turnably support the said shafts, and means to rotate various groups of rollers at different speeds.

3. In a device for the wet treatment of hanks and the like, a number of rotary shafts to movably suspend the hanks to be treated, groups of rollers to turn the said shafts said rollers being so arranged that different groups rotate at different speeds, and a driving gear to impart rotation to the said rollers.

4. In a device for the wet treatment of hanks and the like, a number of rotary shafts to movably suspend the hanks to be treated, and rollers arranged in groups to turnably 2 1 1,72s,e7e

support the said shafts, said rollers being of mutually varying diameters to impart different rotary speeds to the said shafts and the hanks suspended therefrom.

5. In a device for the wet treatment of hanks and the like, a number of rotary shafts to suspend the hanks to be treated, ,rollers arranged in groups to loosely and turnably support the said shafts, and gear wheels 10 adapted to rotate the said rollers at difierent speeds.

6. In a device for the treatment of banks and the like, a number of rotary shafts to movably suspend the hanks to be treated,

rollers arranged in groups to loosely and turnably support the said shafts, and gear wheels adapted to rotate the said groups of rollers at mutually difiierent speeds, the gear wheels for each group of rollers having a difi'erent transmission ratio from that of the gear wheels of other groups of rollers.

7. In a device for the wet treatment of hanks and the like, a number of rotary shafts to movably suspend the banks to be treated,

rollers arranged in groups to loosely and turntably support the said shafts, and differently pitched worms and worm wheels for the said groups of rollers adapted to drive the said rollers and the shafts suspending the hanks at mutually differing speeds.

In testimony whereof I a'flix my signature.
